<p>GLib doesn't force any particular localization method upon its users.
But since GLib itself is localized using the <code class="function">gettext()</code> mechanism, it seems
natural to offer the de-facto standard <code class="function">gettext()</code> support macros in an
easy-to-use form.</p>
<p>In order to use these macros in an application, you must include
<code class="literal">&lt;glib/gi18n.h&gt;</code>. For use in a library, you must include
<code class="literal">&lt;glib/gi18n-lib.h&gt;</code>
after defining the <code class="literal">GETTEXT_PACKAGE</code> macro suitably for your library:</p>
<div class="informalexample">
  <table class="listing_frame" border="0" cellpadding="0" cellspacing="0">
    <tbody>
      <tr>
        <td class="listing_lines" align="right"><pre>1
2</pre></td>
        <td class="listing_code"><pre class="programlisting"><span class="gtkdoc ppc">#define GETTEXT_PACKAGE</span> <span class="gtkdoc pps">&quot;gtk20&quot;</span><span class="gtkdoc ppc"></span>
<span class="gtkdoc ppc">#include &lt;glib/gi18n-lib.h&gt;</span></pre></td>
      </tr>
    </tbody>
  </table>
</div>

<p>
For an application, note that you also have to call <code class="function">bindtextdomain()</code>,
<code class="function">bind_textdomain_codeset()</code>, <code class="function">textdomain()</code> and <a class="link" href="glib-running.html#setlocale" title="Locale"><code class="function">setlocale()</code></a> early on in your
<code class="function">main()</code> to make <code class="function">gettext()</code> work. For example:</p>
<div class="informalexample">
  <table class="listing_frame" border="0" cellpadding="0" cellspacing="0">

<p>
where <code class="literal">DATADIR</code> is as typically provided by automake.</p>
<p>For a library, you only have to call <code class="function">bindtextdomain()</code> and
<code class="function">bind_textdomain_codeset()</code> in your initialization function. If your library
doesn't have an initialization function, you can call the functions before
the first translated message.</p>
<p>The
<a class="ulink" href="http://www.gnu.org/software/gettext/manual/gettext.html#Maintainers" target="_top">gettext manual</a>

<pre class="programlisting">#define             Q_(String)</pre>
<p>Like <a class="link" href="glib-I18N.html#gettext-macro" title="_()"><code class="function">_()</code></a>, but handles context in message ids. This has the advantage
that the string can be adorned with a prefix to guarantee uniqueness
and provide context to the translator.</p>
<p>One use case given in the gettext manual is GUI translation, where one
could e.g. disambiguate two "Open" menu entries as "File|Open" and
"Printer|Open". Another use case is the string "Russian" which may
have to be translated differently depending on whether it's the name
of a character set or a language. This could be solved by using
"charset|Russian" and "language|Russian".</p>
<p>See the <a class="link" href="glib-I18N.html#C-:CAPS" title="C_()"><code class="function">C_()</code></a> macro for a different way to mark up translatable strings
with context.</p>
<p>If you are using the <a class="link" href="glib-I18N.html#Q-:CAPS" title="Q_()"><code class="function">Q_()</code></a> macro, you need to make sure that you pass
<code class="literal">--keyword=Q_</code> to xgettext when extracting messages.
If you are using GNU gettext &gt;= 0.15, you can also use
<code class="literal">--keyword=Q_:1g</code> to let xgettext split the context
string off into a msgctxt line in the po file.</p>

<pre class="programlisting">const <a class="link" href="glib-Basic-Types.html#gchar" title="gchar"><span class="returnvalue">gchar</span></a> *
g_dgettext (<em class="parameter"><code>const <a class="link" href="glib-Basic-Types.html#gchar" title="gchar"><span class="type">gchar</span></a> *domain</code></em>,
            <em class="parameter"><code>const <a class="link" href="glib-Basic-Types.html#gchar" title="gchar"><span class="type">gchar</span></a> *msgid</code></em>);</pre>
<p>This function is a wrapper of <code class="function">dgettext()</code> which does not translate
the message if the default domain as set with <code class="function">textdomain()</code> has no
translations for the current locale.</p>
<p>The advantage of using this function over <code class="function">dgettext()</code> proper is that
libraries using this function (like GTK+) will not use translations
if the application using the library does not have translations for
the current locale.  This results in a consistent English-only
interface instead of one having partial translations.  For this
feature to work, the call to <code class="function">textdomain()</code> and <a class="link" href="glib-running.html#setlocale" title="Locale"><code class="function">setlocale()</code></a> should
precede any <a class="link" href="glib-I18N.html#g-dgettext" title="g_dgettext ()"><code class="function">g_dgettext()</code></a> invocations.  For GTK+, it means calling
<code class="function">textdomain()</code> before gtk_init or its variants.</p>
<p>This function disables translations if and only if upon its first
call all the following conditions hold:</p>
<div class="itemizedlist"><ul class="itemizedlist" style="list-style-type: disc; ">
<li class="listitem"><p><em class="parameter"><code>domain</code></em>
 is not <a class="link" href="glib-Standard-Macros.html#NULL:CAPS" title="NULL"><code class="literal">NULL</code></a></p></li>
<li class="listitem"><p>textdomain() has been called to set a default text domain</p></li>
<li class="listitem"><p>there is no translations available for the default text domain
and the current locale</p></li>
<li class="listitem"><p>current locale is not "C" or any English locales (those
starting with "en_")</p></li>
</ul></div>
<p>Note that this behavior may not be desired for example if an application
has its untranslated messages in a language other than English. In those
cases the application should call <code class="function">textdomain()</code> after initializing GTK+.</p>
<p>Applications should normally not use this function directly,
but use the <a class="link" href="glib-I18N.html#gettext-macro" title="_()"><code class="function">_()</code></a> macro for translations.</p>
